Did a little searching - no good.
So here is the question: will the fork from SRX400 fit in XJ600? Will there be any problems? Seems that either of forks is 38mm in diameter, but i dont know about all the other dimensions. Here is photo with dimensions painted:
Any ideas? Maybe there is a way to install more rugged (bigger in diameter) fork, like FZR600? I've seen the thread about FZR600 fork swap but so far found none locally.
